CAUTION
- Do not replace the battery of the DTSX3000 and the battery of the CPU module in
explosive atmospheres.
- Do not short circuit the wire when replacing the battery.
Short-circuiting the battery may result in generated heat , electrolyte leakage and
battery damage.
- Follow the procedure described in the FCN/RTU manual when replacing the battery
of the CPU module. You will need to save retentive data, set system date and time,
transit to online mode and perform other operations from a Web browser.
- When attaching the DTSX3000 to the Base module, ensure that the gasket is
properly in place at the back of the DTSX3000.
- Before attaching the DTSX3000 to the Base module, ensure that the SD card is
locked in place at the back of the DTSX3000.

Handling Precautions Regarding the Battery
This device uses a lithium battery. The lithium battery is structurally sealed by glass seal
and laser welding, and lithium and thionyl chloride are charged inside. Therefore,
improper handling may cause the battery to leak electrolyte, generate heat, burst or
ignite, resulting in injury or damage to the equipment. To prevent these problems, be
sure to observe the following precautions.
- Never charge the battery.
If the battery is charged, the electrolyte inside the battery may bubble or the internal
pressure may rise due to generated gas. When this happens, the battery may leak
electrolyte, generate heat, burst or ignite.
- Do not use this battery except for the specified purpose.
The terminal structure or other aspect of the battery may be incompatible with the
equipment, resulting in poor contact or nonconforming voltage. When this happens,
the battery may leak electrolyte, generate heat, burst or ignite.
- Do not put the battery into fire, or heat, disassemble or modify the battery.
The glass seal, vent (safety valve) or other parts of the battery may be damaged,
causing the battery to leak electrolyte, generate heat, burst or ignite.
- Do not connect the positive and negative electrodes of the battery in reverse.
Abnormal reaction may occur due to accidental charging or short-circuiting, causing
the battery to leak electrolyte, generate heat, burst or ignite.
- Electrolyte is harmful to the human eyes. If electrolyte has gotten into the eye, do
not rub but rinse the eye thoroughly under clean running water and then
immediately seek medical attention.
- If electrolyte has been licked, immediately rinse the mouth and consult a doctor.
- Do not connect the positive and negative electrodes of the battery using a wire,
etc., or transport or store the battery with a metal necklace, hairpin, etc.
The battery will be shorted and excessive current may flow, causing the battery to
leak electrolyte, generate heat, burst or ignite.
